By April 2025 the municipality reported more than 21,000 active users and over 2.2 million kilowatt-hours of electricity costs offset for more than 1,500 vulnerable households

the widely repeated 32% drop in congestion is a first-month figure published by the app vendor

Published field: lesson · verbatim
Mapping: mapped · no interpretation or interpolation added by this passport

Known limits of this passport

Publisher names and source languages have not yet been classified; domains are recorded without guessing.
Existing source notes are descriptive locators, not page- or paragraph-exact citations.
A missing archive, publication date or content hash is shown as null rather than inferred.
The project-level evidence grade ranks the strongest source in the entry; it is not a truth score for every claim.
